TBU-DF085-200-WH

Overview

The Bourns TBU-DF085-200-WH is a dual-channel high-speed protector (HSP) designed for circuit protection. It features an 850V peak pulse voltage rating and a 200mA trigger current. The device operates within a temperature range of -55°C to +125°C and utilizes a DFN surface-mount package. This silicon-based solid-state resettable component acts as a series barrier to block transient currents.

Feature Summary

Provides effective barrier against short circuits, overvoltage transients, and battery cell failures
Utilizes MOSFET detection circuit triggering for fast response during transient events
Offers bidirectional protection capabilities for sensitive electronic components

Applications

RS-485 interface protection
General-purpose electronic equipment
Factory automation systems

Procurement Notes

Verify the specific datasheet for the TBU-DF085-200-WH model to confirm exact electrical characteristics and pinout configuration. Ensure compatibility with the intended PCB layout and thermal management requirements. Cross-reference with official Bourns documentation to validate performance under expected surge conditions.

Selection Notes

Select this component for applications requiring robust protection against high-energy surges in industrial environments. The dual-channel design supports differential signaling lines effectively. Consider the operating temperature range and package size when integrating into compact or harsh-condition designs.

Part Context

This part belongs to the Bourns TBU® High-Speed Protector family, which includes various series such as TBU-CA, TBU-DT, and TBU-RS. The TBU-DF series specifically offers dual-channel protection with multiple pulse voltage and trigger current options, catering to diverse interface protection needs.

Replacement Considerations

Consult official Bourns substitution guides for equivalent parts within the TBU-DF series or other compatible HSP models. Verify that any substitute matches the 850V pulse voltage and 200mA trigger current specifications.
